Last month I replaced the left emergency brake cable on my 1974 Super Beetle. The new cable went right in and through the tunnel. Today I tried to replace the right cable but the threaded end will not go all the way up the tube. I tried greasing the cable and tube but the threaded end hits the tunnel and won't go any further. I had to put the damaged original cable back in. If anyone has been able to replace the right cable let me know what you did. There doesn't appear to be any damage to the tube or tunnel.
Thank you
